The news broke down like a bomb. Salazar should have provided active testosterone and manipulated doping tests. Among those active in his stable are Sifan Hassan, who took gold at 10,000 meters the day before. The Dutchman was shocked at the information which meant that the coach was banned from the World Cup.

SVT Sports expert now responds to the shaking of the athletics world championship.

- It is an extremely big scandal for the brand. He is ultimately responsible for the entire NOP project, but also for those active under his leadership. Unfortunately, they get a dark cloud over them, says Alhaji Jeng.

Tonight, Salazar's adopters Donavan Brazier and Clayton Murphy run the 800 meters final. Hassan said she was disturbed by the USDA's timing to release the information now.

- It is very regrettable that there are irregularities in major championships. It is not this type of publicity that athletics needs. On the other hand, USADA sends a clear signal that they have been actively working and are taking action to overcome the doping prevailing in athletics, says Alhaji Jeng.
